Hey there, I want to buy an iPad soon. I will definitely be getting the WiFi model, because I already own an iPhone with unlimited 3G and don't feel the need for two 3G devices. Only thing I'm not sure about is which capacity to buy. Things I will be using it for: - iBooks (my Uni also only uses digitalized pdf-books) - other e-reading (Kindle, magazines etc.) - surfing / mail - gaming - no music or movies I guess it's quite safe to say I won't be needing 64Gb, but will 16GB be sufficient or should I invest the 100 more to buy the 32GB model? Thanks!
